Hi Larry;

I'm sure there are alot more qualified members here to answer this/your question. I think the reason the ABS is kicking in faster is because you have less rubber/traction on the ground and therefore the ABS is kicking in sooner to keep the tires from locking up. See if this makes any sense at all to you. The more added tire pressure the rounder the tire becomes and the less tread is on the ground so the ABS is activating quicker to control tire/brake lock-up.

Thats what i think. As far as it being Dangerous I really honestly could not answer that. I think you are going to find that on this specific (Civic-Forum) you are more than likely going to have all kinds of Opinions regarding your question. You in the end are going to have to decide what you think is best and safest for you and your family in your car.

One more comment, I can see that going down hill and added tire pressure would activate the ABS quicker because of the situation.

I think it is going to ultimately come down to this as far as a decision on your part. Less FE with the tires set back to the Factory Specs. or keep the tire pressure increased and live with the ABS kicking in quicker.

Your decision:

HTH;
